Therefore, it is suggested that the newly isolated organism represents a novel species, for which the name Pedobacter panacis sp. nov is proposed with the type strain designated as DCY108^T (=CCTCCAB 2015196^T = KCTC 42748^T).     

<Emphasis Type="Italic">Leifsonia flava</Emphasis> sp. nov., a novel actinobacterium isolated from the rhizosphere of <Emphasis Type="Italic">Aquilegia viridiflora</Emphasis>

SYP-B2174^T is a yellow-pigmented, Gram-positive, non-motile, and rod-shaped actinobacterium isolated from the rhizospheric soil of Aquilegia viridiflora Pall. collected from the Xinjiang uygur autonomous region of China. The strain’s growth temperature ranges from 1 to 35°C, with an optimal growth being observed at 28°C. Growth occurs from 0 to 5% NaCl and at pH 6–8, with optimal growth being observed in 1% NaCl at pH 7. Comparative 16S rRNA gene sequence-based phylogenetic analysis placed the strain in a clade with the species Leifsonia kafniensis JCM 17021^T and Leifsonia psychrotolerans DSM 22824^T with similarities of 97.8 and 97.6%, respectively. The DNA-DNA hybridization values of the strain SYP-B2174^T to its closest phylogenetic neighbors were significantly lower than 35.7%. The strain was identified as a novel species of the genus Leifsonia judging by the coryneform morphology, peptidoglycans based upon 2,4-diaminobutyric acid, principal phospholipids phosphatidylglycerol and diphosphatidylglycerol, major menaquinone MK-11, predominant fatty acids of anteiso-C_15:0, anteiso-C_17:0, and iso-C_16:0, and a DNA G + C base composition of 68.7 mol%, for which the name Leifsonia flava sp. nov. is proposed. The type strain is SYP-B2174^T (= CGMCC 1.15856^T = DSM 105144^T = KCTC 39963T).     

<Emphasis Type="Italic">Spirosoma daeguensis</Emphasis> sp. nov., isolated from beach soil

A Gram-stain-negative, non-motile, non-spore-forming, rod-shaped, aerobic bacterium, designated 15J9-6^T, was isolated from beach soil on Jeju Island, South Korea. Strain 15J9-6^T, grew at 10–30°C (optimum growth at 25°C) and pH 7–8 (optimum growth at pH 7) on R2A, NA, and TSA agar. Phylogenetically, the strain was closely related to members of the genus Spirosoma (92.3–90.1% 16S rRNA gene sequence similarities) and showed highest sequence similarity to Spirosoma panaciterrae DSM 21099^T (92.3%). The G+C content of the genomic DNA of strain 15J9-6^T was 45.7 mol%. The strain contained phosphatidylethanolamine, two unidentified aminophospholipids, an unidentified phospholipid, and an unidentified lipid as the major polar lipids; menaquinone MK-7 as the predominant respiratory quinone and summed feature 3 (C_16:1 ω6c/C_16:1 ω7c; 30.1%), C_16:1 ω5c (23.1%), iso C_15:0 (13.3%), and C_16:0 (8.4%) as the major fatty acids which supported the affiliation of strain 15J9-6^T to the genus Spirosoma. The results of physiological and biochemical tests allowed genotypic and phenotypic differentiation of strain 15J9-6^T from recognized Spirosoma species. On the basis of its phenotypic properties and phylogenetic distinctiveness, strain 15J9-6^T represents a novel species of the genus Spirosoma, for which the name Spirosoma daeguensis sp. nov. is proposed. The type strain is 15J9-6^T (=KCTC 52036^T =JCM 31995T)     

<Emphasis Type="Italic">Sphingomonas hunanensis</Emphasis> sp. nov., isolated from forest soil

A novel Gram-negative, catalase- and oxidase-positive, strictly aerobic, non spore-forming, rod-shaped bacterium, designated strain JSM 083058^T, was isolated from non-saline forest soil in Hunan Province, China. Growth occurred with 0–8% (w/v) NaCl (optimum, 0.5–3%) at pH 6.0–10.0 (optimum, pH 7.0) and at 5–35°C (optimum, 25–30°C). Phylogenetic analysis based on 16S rRNA gene sequences indicated that strain JSM 083058^T fell within the cluster comprising species of the genus Sphingomonas, clustering with Sphingomonas aestuarii K4^T, with which it shared highest 16S rRNA gene sequence similarity (99.2%). The chemotaxonomic properties of strain JSM 083058^T were consistent with those of the genus Sphingomonas. The predominant respiratory quinone was ubiquinone Q-10, and the major cellular fatty acids were summed feature 8 (C18:1ω7c/C18:1ω6c), C16:0, summed feature 3 (C16:1ω7c/C16:1ω6c) and C17:1ω6c. The polar lipids consisted of diphosphatidylglycerol, phosphatidylcholine, phosphatidylethanolamine, phosphatidylglycerol and sphingoglycolipid. The genomic DNA G+C content of strain JSM 083058^T was 65.5 mol%. The combination of phylogenetic analysis, DNA–DNA relatedness, phenotypic characteristics and chemotaxonomic data supported the view that strain JSM 083058^T represents a novel species of the genus Sphingomonas, for which the name Sphingomonas hunanensis sp. nov. is proposed. The type strain is JSM 083058^T (=CCTCC AA 209011^T = DSM 22213^T).     

<Emphasis Type="Italic">Acinetobacter soli</Emphasis> sp. nov., isolated from forest soil

A non-motile and rod shaped bacterium, designated strain B1(T), was isolated from forest soil at Mt. Baekwoon, Republic of Korea. Cells were Gram-negative, catalase-positive, and oxidase-negative. The major fatty acids were 9-octadecenoic acid (C(18:1) omega9c; 42%) and hexadecanoic acid (C(16:0); 25.9%) and summed feature 3 (comprising iso-C(15:0) 2-OH and/or C(16:1) omega7c; 10.0%). The DNA G+C content was 44.1 mol%. A phylogenetic tree based on 16S rRNA gene sequences showed that strain B1(T) formed a lineage within the genus Acinetobacter and was closely related to A. baylyi DSM 14961(T) (98.6% sequence similarity), followed by A. baumannii DSM 30007(T) (97.4%), A. calcoaceticus DSM 30006(T) (97.0%) and 3 genomic species (96.8 approximately 7.6%). Phenotypic characteristics, gyrB gene sequence analysis and DNA-DNA relatedness data distinguished strain B1(T) from type strains of A. baylyi, A. baumannii, and A. calcoaceticus. On the basis of the evidence presented in this study, strain B1(T) represents a novel species of the genus Acinetobacter, for which the name Acinetobacter soli sp. nov. is proposed. The type strain is B1(T) (= KCTC 22184(T)= JCM 15062(T)).
